with an extension 26 which is pivoted to one end of a member 27 theother end of which is connected to or is formed integral with the strap28 of an eccentric 29 whereby said link 7, 26, is rocked thereby,impartingoscillations to the looper carrier 1 longitudinally of themachine and at the same time imparting the required liftthereto.

The swinging links 7 maintain the position of the looper carrier 1transversely of the ma chine and by adjusting them to one. side or theother the looper carrier will receive corresponding transverseadjustment. Adjustment o'f said links 7 i will also serve to take up anyslack caused by wear.

The front and rear supports of the looper carrier, that is to say thetrunnion pins 4 in front andthe spindle 14 at the rear, are as alreadystated, as far apart as the dimensions of In order to vary the amountorextent of lift imparted to the looper 3 all'that'is neces sary is toloosen the clamp 12 (by screw 80) referred to and to adjust the stud 13-carried 1 therein (and consequently the bearing 2, spindle 14, and upperend of the link 15 mounted on said spindle) forwardly or'backwardly.This will cause the link 15, during the operation of the machine, toswingthrough a greater or less angle according to the adjustinentmade. iV V In 'o-rder to vary the lowest position to which the looper reacheswithout altering the amount of its lift, the stud 11 in the verticallydisposed bearing 10 will be adjusted, a set screw 31 being providedtosecure the stud in "adjusted position. Inorder that a very fineand'precise adjustment may be obtained,

we p'rovidethe stud 11 or clamp 12 with two lugs 32 the upper and lower'faces ofwhich are respectively engaged by collars formed integrallywith a second stud 38 that is screwed into thema'chine' casing so thatby screwing it up or down the clamp will be correspondingly adjusted.The-upper end 3 1 of said collars may be suitably formed to be engagedby a screwdriver orspanner, 1 The looper bar ais provided justable'collar35.,and-a set screw.- Said bar is entered intothe tubular loopercarrier un til said collar abuts against the front end of 'the carrierand is secured-in positioniby a collar36 and set screw on its rear'end,which] collar abuts againsta shoulder on the. car- -rier. 1

The collar on therear end of the bar is pref with an adbe understoodthat we do not limit the scope of our invention thereto.

What we claim as new, is z" .1. In anoversea-ming machine for fur andgloves, the combination of a main frame, a power shaft thereon, ahorizontally movable needle, a looper above the needle and havingforward and backward, up and down, and

sidewise movements, 2; looper carrier, .means for supporting the forwardend of the looper carrier comprising a pair oflinks, supported fromtheframe and which aremut-ually adjustable for supporting the loopercarrier between them. and operably connected with,

the power shaft for receiving a swinging mo tion, and means forsupporting the rear end of the looper carrier comprising alongitudinally adjustable pin or stud supported from the frame so as tobe parallel with theneedle and h'aving abearing, and ailink journaled inand depending from the bearing, and connected with the looper carrier.
